問題提起がなされている。 Conventionally, there are various methods for constructing underwater foundations, but in order to construct a caisson foundation underwater, an artificial island is first constructed. However, in the case of deep water, the construction island would be very large, and the time required to work at sea would be long, and the efficiency of construction would be low. Problems have been raised such as not being able to secure enough supplies.

工法を提供しようとするものである。 In view of the above-mentioned circumstances, the present invention enables the construction of a caisson foundation simply and quickly even in deep water and in cases where the support layer in the underwater ground is deep, thereby significantly improving construction efficiency. The purpose of this project is to provide an embedded steel plate cell caisson construction method that can improve safety.
以下、本発明に係る工法を図面の記載に基いて

面に取付けられている。 The steel plate cell 1 used in the construction method of the present invention has a required diameter and a height corresponding to the water depth at the pouring site and the depth of the supporting layer, and is prepared in advance at a factory or work yard near the site. It was manufactured. Note that the reinforcing rib plate of the steel plate cell 1 is attached to the outer surface.

エネルギーを伝えるものとする。 When constructing a caisson foundation in the sea using the steel plate cell 1, the steel plate cell 1 is transported to a casting site by a crane ship, barge, etc., and positioned. Next, the steel plate cell 1 is rapidly driven into the seabed ground a using a vibration driving method, and the seawater inside is immediately expelled, and earth and sand are poured in to fill the steel plate cell 1 with water pressure from the outside and to prevent the steel plate cell 1 from being destroyed by water pressure from the outside. Make them maintain their posture. Also, after filling,
If necessary, an underwater solidifying chemical solution 2 is injected around the embedded portion of the steel plate cell 1 to completely seal the steel plate cell 1. The apparatus for driving the steel plate cells 1 by the vibration driving method is one in which a required number of vibrating pile drivers are synchronously driven by an interlocking system to transmit uniform vibration energy to the steel plate cells 1.

クリート６が施工される。 As mentioned above, once the installation work of the steel plate cell 1 is completed, the underground continuous wall 3 is constructed along the inner surface of the steel plate cell 1, and the underground continuous wall 3 is further connected to the underground continuous wall 3 in a cross shape. A continuous wall 4 is constructed and a caisson foundation 5 is constructed. A concrete frame 6 is constructed on the caisson foundation 5.

水の汚濁を回避することができる。 In addition, leakage of muddy water from the embedded part due to muddy water pressure in the steel plate cell 1 can be prevented by injecting the underwater solidifying chemical solution 2 around it, and the overflow of muddy water from the upper end of the steel plate cell 1 can be prevented. This can be prevented by lowering the construction base b by about 1 to 2 m below the external water level c. By taking this measure, it is possible to avoid seawater pollution.

のである。 The steel plate cell 1 manufactured in a factory or a work yard near the site can be manufactured with a height that corresponds to the water depth of the pouring site and the depth of the supporting layer. Since it can be transported as is to the pouring site using a crane boat, barge, etc., construction can be carried out even in deep water and deep supporting layers. After the steel plate cell 1 is installed, the caisson foundation 5 can be constructed by simply constructing the underground continuous walls 3 and 4 within the steel plate cell 1. This enables quick construction. Therefore, safe construction can be carried out especially in response to changeable marine weather conditions, and the construction method according to the present invention greatly contributes to the promotion of marine development.

る。 In summary, the present invention transports and positions prefabricated steel plate cells to a pouring site,
This steel plate cell is rapidly driven into the underwater ground using a vibratory driving method, and after immediately filling it with earth and sand, an underground continuous wall is constructed within the steel plate cell to construct a caisson foundation. Because it is an embedded steel plate cell caisson construction method, it is possible to construct a caisson foundation simply and quickly, even in deep water or with a deep support layer in the underwater ground, which improves construction efficiency. This has the effect of significantly improving safety and improving safety.
